C) 11 a4 (D) B We have learned, by examining the two previous main lines, that Black can defend rather easily if he is allowed to play ... lDd7. With 11 a4 White prevents this since 11...lDd7 is now met by 12lDxc6 J-b7 13 axb5. Now we split the variations into three further main lines: Cl: 11 ... c5 134 C2: 11 ... J-b7 136 C3: 1l ... h3!? 138 Cl) 11 ... c5 With this rather provocative move, Black claims that White's previous move was not really threatening anything. 12lDg4! Regarded as White's best since 11.. .c5 was launched in the late 1980s. Deliberately removing the pride and joy of White's position from e5 is here justified for various reasons. First of all, its supporter on d4 is about to be undermined, but, secondly, and not less importantly, Black has completely opened his queenside, and so it is logical to begin an attack here by first forcing Black's queen to a less favourable position. However, the two captures on b5 should also be investigated: a) 12 lDxb5? is simply good for Black: 12 ... cxd4 13 lDc7+ ~d8 14 'iVxd4+ lDd7 150-0-0
